FLUID CONTAINER.

Application filed March 13, 1916, Serial No. 83,893. Renewed May 16, 1923.

To all whom it may concern.

Be it known that I, JOHN HAYs HAM- MOND, J12, a citizen of the United States, and a resident of the city of Gloucester, county of Essex, and State of Massachusetts, have invented certain new and useful Improvements in Fluid Containers, of which the following is a specification.

Some of the objects of this invention are to provide in a container or receptacle for holding a fluid, or liquid, improved means whereby a perforation or other opening made in a normally imperforate portion of the receptacle or container by a rapidly moving bullet or other projectile, or by other means, may be quickly sealed or covered to prevent the escape of fluid through such perforation or opening; and to provide other improvements as will appear hereinafter.

In the accompanying drawings, Fig. 1 is a diagrammatic plan view of a receptacle constructed in accordance with thisinvention; Fig. 2 is a side elevation of the same;

Fig. 3 a section along line 33 of Fig.1; Fig. 4 a section along line 44 of Fig. 2; and Fig. 5 a section along line 55 of Fig. 1.

Referring to the drawings, one embodiment of this invention comprises a substanwith the opposite ends of the botom wall 11.

The top wall 16' is provided with an inlet 17 through which the tank mav be filled with a fi1uid or liquid or other substanceor mater1a Surrounding and preferably fixedly secured to the bottom wall 11 and side and end walls 12 to 15 of the tank 10, isa layer or covering of material 20, such, for instance, as leather or other :material, but pre'ferablysuch a material as will not form a lip or burr, or which will form only a readily yielding lip or burr when pierced by a bullet or other rapidly moving object.

Surrounding and slidably resting against that portion of the layer or covering of leather or other material which covers the 1,529,064 PATENT OFFICE'p bottom wall 11 and the end walls 1 1 and l5,

is a strip of sheet material, such, for instance, as oil silk or any other suitable material which is impermeable to fluids. The longitudinal edges 26 and 27 of this strip 25 are parallel to each other and arranged in planes coincident with the outer side surfaces of the portions 'of the covering 20 which are secured to the side walls 12 and 13 of the tank 10. The opposite ends of this strip 25 are wound about two cylindrical horizontal parallel drums 30 and 31 which are rigid and coaxial with spindles 32 and 33 respectively which are rotatably supported in bearings provided therefor in rigid brackets 34 and 35 which are fixedly secured to the walls of the tank 10, whereby the drums 30 and 31 are mounted to rotate about fixed substantially parallel horizontal axis. I

Contacting with and covering the outer surface of the strip 25 and holding the strip 25 slidably against the outer surface ofthe inner layer 20 is an outer layer 36of material, the longitudinal edges 37'and 37 of which are parallel and flush with the longitudinal edges of the strip 25'and the end edges '38 and 39 which are flush with the upper horizontal surface of the tank. This outer layer 36 may be of the same material as the inner layer 20 or of any other suitable material and is held in place by means of screws extending through projections on the brackets 3 1 and 35 and by other means as will appear hereinafter.

Slidably contacting against the outer. ver

tical side surfaces of the inner layer 20 .re-

spectively, are two horizontally movable strips and 510i sheet material impervious to fluid, which may be of the same material as the strip 25 surrounding the end walls. 51 are wound respectively upon two pairs of vertical drums 52, 53, and 54:, 55, which are rigid and coaxial with vertical spindles 56, 57, and 58, 59, respectively, the upper ends of which are mounted to rotate in bearings provided therefor in the brackets .34 and 35 and the lower ends of which are mounted to rotate in bearings provided therefor in rigid brackets 60 and 61 fixedly secured to the under surface of the outer layer '36 by means of screws 62 and 63' or other fastening means, the vertical drums 52, 53, 54 and beingthus mounted to r0- The ends of these side strips 50 and tate-about-ifixed verticalraxes coincident with theirlongitudinal axes. Contacting withthe outer surfaces of the horizontally movable side strips 50.and 51 are two vertical 1 5 side layers 65 and 66 which may boot the same material as the inner layer ori'cover ing of the tank 10. These side layers 65 and 661 are rectangular. in shape tand ser cured along their upper edges by screws 10. 67 and 68 to l the brackets i'la and 35 and along their lower edges by screws 69aud'7O .1 to tl1e-brackets60- an'd61.

Any suitable means may be provided for winding up one of theg h'orizontal drums 30 1501' 31 andone oteach of the pairs of vertical drums' 52, 53; and5 i, 55, so as to move thecorresponding strips of fluid impermeable material, but in'vt'he form. of this in" ventionvillustrated means areprovided for 0 movingrall of thesestrips simultaneously," i-andithe means" shownfor this purpose ineludes three imo-tion transmitting drums 7 5,
